During his term as first chancellor of West Germany, Konrad Adenauer lived in Bad Honnef, as it was near Bonn, then the capital of the Federal Republic of Germany. Also, German politician and leader of the Free Democratic Party Guido Westerwelle was born in Bad Honnef. Since the 1980's Bad Honnef has developed to an important place for conferences in Germany.
